Sorry to bother, but there are 3 different Korean ROMs KTF, LGT and SKT, which one do you recommend downloading?
And can I download the latest Android 11 and flash that one directly?

Any one doesn’t make different
And yes you can go straight to 11

in the page sort the update by date and chose the newest one latter if you want to update you can flash again but all data will be erased
I couldn’t make the ota To work

Gents,
Could you please advise how to remove Warning message which appears after every restart:
'current version is not available for user. can't find matched carrier. Check NT-Code: FFFFFF : 84'

Go to hidden menu then go to mid info change tn number to Korean models
But you losses the 5g network

so try multiple tn number until you find the one good with your carrier
tn numbers

Why would you need to flash a demo software, when you could just flash a korean software

 

[0x0null]

For those that dont like cmd, you can use this LGUP and dll
LGUP 16 GUI

Should you find a root for it Magisk may fix it

No way,friend.Just because for root,needed to be unlocked bootloader,but on demo version this is impossible,cus he doesn't give device id for unlocking
